Living Among Wildlife: Elevating Human-Wildlife Interactions And Coexistence, Bridget Rebecca Murphy

Graduate Student Portfolios, Professional Papers, and Capstone Projects

After a semester of learning, both in class and in nature, my writing honed in further on this human-nature divide. To me, I see humans as part of nature – as we are mammals, animals, part of the food chain, biological beings no higher than others on our planet. We have simply constructed this false narrative around us within our societies, minds and media that embeds this division between us and nature, between us and wildlife. Humans have been managing, stewarding, living off and within landscapes for thousands of years. As time and technology evolved, a lot of people began …

Mitochondrial Metabolism In Blood More Reliably Predicts Whole-Animal Energy Needs Compared To Other Tissues, Stefania Casagrande, Maciej Dzialo, Lisa Trost, Kasja Malkoc, Edyta T. Sadowska, Michaela Hau, Barbara J. Pierce, Scott R. Mcwilliams, Ulf Bauchinger

Biology Faculty Publications

Understanding energy metabolism in free-ranging animals is crucial for ecological studies. In birds, red blood cells (RBCs) offer a minimally invasive method to estimate metabolic rate (MR). In this study with European starlings Sturnus vulgaris, we examined how RBC oxygen consumption relates to oxygen use in key tissues (brain, liver, heart, and pectoral muscle) and versus the whole-organism measured at basal levels. The pectoral muscle accounted for 34-42% of organismal MR, while the heart and liver, despite their high mass-specific metabolic rate, each contributed 2.5-3.0% to organismal MR. Despite its low contribution to organismal MR (0.03-0.04%), RBC MR best predicted …

A Year Of Wins For Farmed Animals, Lewis Bollard

General – Farm Animal Issues

Although the European Union shelved its ambitious farmed animal welfare reforms, there were other “wins” for farmed animals in 2023. There were 130 new corporate pledges to eliminate cages for laying hens and the worst abuses of broiler chickens. So far, over 1,000 corporate pledges have been fully implemented, and 39% of American hens, 60% of European hens, and 80% of British hens are cage-free, up from 6%, 41%, and 48%, respectively, a decade ago. The US Supreme Court upheld California’s Proposition 12, which bans the sale of eggs, pork, and veal from caged animals and their offspring in California. …

Status Survey Of Eight Rare Aquatic Macroinvertebrates In East Texas, Alexandra Randall

Biology Theses

Freshwater is essential to human existence. The health of each freshwater source is connected to the survival of pollution intolerant species of aquatic macroinvertebrates in the orders Ephemeroptera, Plecoptera, and Trichoptera (EPT taxa). A higher presence of EPT taxa equates to better water quality because their water bound larvae assist in maintaining clean freshwater environments and will not survive in highly polluted water. Human disruption to natural environments is causing increases in polluted freshwater, leading to decreases in the presence of EPT taxa. Texas Parks and Wildlife Department documentation shows major concern for the populations of eight EPT species of …

On Some Teratological Scorpions In The Natural History Museum, London And Checklist Of The Scorpiological Literature On Morphological Anomalies (Arachnida: Scorpiones), Danniella Sherwood, Luis F. De Armas

Euscorpius

Whilst undertaking curation in the collections of the Natural History Museum, London, the senior author came across a jar of scorpions marked ‘scorpions with curled feet’. Further investigation showed this jar was full of scorpions with teratological anatomy. We hereby document and illustrate all of the specimens and discuss their respective anomalies. Furthermore, a comprehensive checklist of the literature on anomalies in scorpions, including giving the life stage and sex where known, is compiled for the benefit of future workers.

Combined Purebred And Crossbred Genetic Evaluation Of Columbia, Suffolk, And Crossbred Lamb Birth And Weaning Weights: Systematic Effects And Heterogeneous Variances, Napoleón Vargas Jurado, David R. Notter, Joshua B. Taylor, Daniel J. Brown, Michelle R. Mousel, Ronald M. Lewis

Department of Animal Science: Faculty Publications

Despite the benefits of crossbreeding on animal performance, genetic evaluation of sheep in the U.S. does not directly incorporate records from crossbred lambs. Crossbred animals may be raised in different environments as compared to purebreds. Systemic factors such as age of dam and birth and rearing type may, therefore, affect purebred and crossbred performance differently. Furthermore, crossbred performance may benefit from heterozygosity, and genetic and environmental variances may be heterogeneous in different breeds and their crosses. Such issues must be accounted for in a combined (purebred and crossbred) genetic evaluation. The objectives of this study were to i) determine the …

Addressing Water Hyacinth (Pontederia Crassipes) Impacts On Aquatic Biota In Lake Okeechobee, Joseph Salerno

All HCAS Student Capstones, Theses, and Dissertations

The incursion of water hyacinth, Pontederia crassipes in Lake Okeechobee has resulted in management systems to be implemented to reduce the coverage of the invasive macrophyte. Its residence in the Lake Okeechobee ecosystem and the effects it has on organisms in the lake, whether it be positive or harmful is unknown. This study attempted to assess the potential effects that water hyacinth has on aquatic biota in Lake Okeechobee. Biotic data were collected on open water, water hyacinth covered, and native vegetation covered habitats via hook-and-line fishing, electrofishing, baited minnow traps, and the sampling of plant roots over a thirteen-month …

Effects Of Wet Aging On Water-Soluble Flavor Compounds, Descriptive Flavor, Consumer Acceptability, And Willingness-To-Pay Of Beef Longissimus Lumborum Steaks, Shangshang Wang

Theses and Dissertations

This study examined the effects of wet aging on water-soluble flavor compounds, descriptive flavor, consumer acceptability, and willingness-to-pay of beef strip steaks. Twenty USDA Select boneless beef loins (NAMP #180) were dorsally divided into four equal portions, which were randomized to receive either 0, 7, 14, or 21 d of wet aging. Short-chained peptide concentration increased from 4.11 mg/g on d 0 to 5.12 mg/g on d 7 (P = 0.011) and subsequently increased to 7.14 mg/g on d 21 (P < 0.001). Cooked beef contained 1.85 mg/g less short-chained peptides than raw beef (P < 0.001). Wet aging for 21 d increased the concentrations of amino acids, which are precursors for the Maillard reaction, including methionine, threonine, cystine, serine, tryptophan, and phenylalanine (P < 0.001). Wet aging decreased the nucleotide concentrations (P ≤ 0.003) and increased hypoxanthine concentration, a compound that imparts bitter flavor (P …

Increased Coding Potential Of Bovine Herpesvirus 1, Victoria Jefferson

Theses and Dissertations

Bovine respiratory disease (BRD) costs the cattle industry millions of dollars in costs in treatment and loss every year in the United States. A significant pathogen often contributes to BRD is Bovine Herpesvirus 1 (BoHV-1), a double stranded DNA virus with the ability to establish latency in the trigeminal ganglia and neurons. Primary infection with BoHV-1 results in immunosuppression that increases the risk of secondary bacterial infection and pneumonia. Because herpesviruses infect their hosts for life and can be reactivated in times of stress, BoHV-1 can present a recurring risk of BRD. The following research aims to expand the knowledge …

Advancing Salamander Conservation Efforts In Zoos And Aquaria Through Assisted Reproductive Technologies (Art), Devin Marie Chen

Theses and Dissertations

Salamanders are one of the most at-risk taxa in the world due to habitat destruction, pollution, climate change, invasive diseases, and more. This has led to a need for conservation breeding programs that are often associated with zoos and aquaria. Salamanders can be difficult to breed in captivity, though, due to their dependence on specific environmental cues and other unknown factors that stimulate sperm and egg production. To overcome these challenges, assisted reproductive technologies (ART) such as exogenous hormone administration, sperm cryopreservation, and in-vitro fertilization have been developed to increase offspring propagation and maintain genetic diversity. If genetically robust populations …

Of Changing Climate And Habitat: Range-Wide Individual Growth And Local Patterns Of Phenology And Landscape Use In A Threatened Pit-Viper, James Helferich

Theses and Dissertations

Over the 21st century, climate change and wetland habitat loss will pose major threats to the Eastern Massasauga (Sistrurus catenatus), a federally threatened and Great Lakes region endemic rattlesnake. I collected capture-recapture data from sites across the range and modeled the effect of climatic variables on growth rate and asymptotic size. I found that high snow residence time was associated with larger asymptotic sizes but slower growth, while high spring precipitation increased growth rate. I then projected future growth and size under different carbon emission scenarios. Given the threat posed by successional encroachment of woody vegetation, I used spatially explicit …
